Oh, and I guess I should give my system info. I'm running with Suse 11.4, which 
has Xen 4.0.2_52-0.2.1 that comes built natively

Subject: Yet Another PCI passthrough question

Hello all,

I'm trying to pass my PCI device through to an HVM. I'm following the steps on 
the xen pci passthrough wiki. 

First I check my pci devices
#lspci -

03:00.0 VGA compatible controller: ATI Technologies Inc Device 671d
03:00.1 Audio device: ATI Technologies Inc Device aa80
04:00.0 Display controller: ATI Technologies Inc Device 671d
04:00.1 Audio device: ATI Technologies Inc Device aa80

Now I edit my grub entry. I'm on SuSE so it's menu.list, not grub.conf #less 

###Don't change this comment - YaST2 identifier: Original name: xen### title 
Xen -- openSUSE 11.4 -
    root (hd0,1)
    kernel /boot/xen.gz vga=mode-0x375 
    module /boot/vmlinuz- 
resume=/dev/disk/by-id/ata-ST3250410AS_6RYJWXM7-part1 splash=silent quiet 
showopts vga=0x375 xen-pciback.hide=(03:00.0)(04:00.0)
    module /boot/initrd-

Now reboot, and look at assignable devices # xm pci-list-assignable-devices

Nothing shows up here. I've also tried adding the xen-pciback.hide line to the 
other module line in grub, that's not doing anything either.

What am I missing? I searched the archives of this list, found this 
(http://lists.xensource.com/archives/html/xen-users/2011-05/msg00517.html) in 
May, same problem. Followed the instructions. Am I missing something dumb?
